Find Out the Average of First Ten Even Numbers.

Explanation:-Formula-Sum of even number = n (n + 1)Where, n = number of natural numbers
Then, the sum of first 10 even number = 10 (10 + 1)
= 10 x 11
= 110
Then, the average of 10 even numbers = 110/10
= 11
Hence, the average of first 10 even numbers is 11.
